Begonia plant named ‘Binos’

ABSTRACT

A new and distinct cultivar of Begonia plant named ‘Binos’, characterized by its upright and mounded plant habit; double flowers that are light pinkish red in color and held above the foliage; and excellent postproduction longevity.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Begonia×hybrida cultivar cultivar Binos.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Begoniaplant, botanically known as Begonia×hiemalis, commercially known asElatior Begonia, and hereinafter referred to by the name ‘Binos’.

The new Begonia was discovered by the Inventor in a controlledenvironment in Ermelo, The Netherlands, in October, 1999, as anaturally-occurring whole plant mutation of Begonia×hiemalis ‘Bastos’,not patented. The new Begonia was observed as a single plant in a groupof flowering plants of the parent cultivar. The selection of this plantwas based on its flower coloration.

Asexual reproduction of the new Begonia by cuttings taken in acontrolled environment in Ermelo, The Netherlands, has shown that theunique features of this new Begonia are stable and reproduced true totype in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Binos’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Binos’. These characteristics incombination distinguish ‘Binos’ as a new and distinct Begonia:

1. Upright and mounded plant habit.

2. Double flowers that are light pinkish red in color and held above thefoliage.

3. Excellent postproduction longevity.

Plants of the new cultivar differ from plants of the parent, thecultivar Bastos, primarily in flower color as plants of the cultivarBastos have darker colored flowers than plants of the cultivar Binos.

Plants of the new cultivar differ primarily from plants of the cultivarBellona, disclosed in U.S. Plant Pat. No. 10,476, in flower color asplants of the cultivar Bellona have darker colored flowers than plantsof the cultivar Binos.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Begonia, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Begonia. The photograph comprises a side perspective view of atypical flowering plant of ‘Binos’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 1995 Edition, except where generalterms of ordinary dictionary significance are used. The aforementionedphotograph and following observations and measurements describe plantsgrown in Ermelo, The Netherlands, under commercial practice in aglass-covered greenhouse. Average day and night temperatures were about20° C. during the first three to four weeks then lowered to an averageday and night temperature of 19° C. until flowering. Four weeks afterplanting rooted cuttings in 12-cm containers, one week of longnyctoperiods of 16 hours was given followed by short nyctoperiods ofeight hours until flowering. Plants used for the photographs and thedescription were about four months old. Measurements and numericalvalues represent averages for typical flowering plants.

Botanical classification: Begonia×hiemalis cultivar Binos.

Commercial classification: Elatior Begonia.

Root description.—Fine, fibrous, well-branched and spreading. Plants ofthe new Begonia have not been observed to form tubers.

Plant description:

Plant form.—Upright and mounded plant habit, inverted triangle; freelybranching with good stem and stem base strength. Flowers are double andabundant. Plants flower continuously.

Growth habit.—Moderate growth rate, vigorous. Suitable for 12 to 15-cmcontainers. Under optimal environmental and cultural conditions, usuallyabout four months are required to produce proportional 13-cm pottedplants from cuttings. Vegetative shoots are formed at basal nodes andflowering shoots are formed at upper nodes.

Plant height.—About 24.5 cm.

Plant width.—About 40 cm.

Leaves.—Arrangement: Simple, alternate. Young leaves, length: About 4.5cm. Young leaves, width: About 5.9 cm. Fully expanded leaves, length:About 9 cm. Fully expanded leaves, width: About 10 cm. Shape:Asymmetrical, more or less reniform. Apex: Acuminate. Base: Cordate.Margin: Doubly serrate. Texture: Glabrous, smooth. Venation pattern:Palmate. Color: Young leaves, upper surface: Darker than 147A. Youngleaves, lower surface: 148C. Fully expanded leaves, upper surface: Muchdarker than 147A. Fully expanded leaves, lower surface: 148C. Venation,upper and lower surfaces: 145B. Petiole length: About 5.75 cm. Petioletexture: Slightly pubescent. Petiole color: 180C.

Flower decription:

Flowering habit.—Double flowers with numerous tepals arranged inaxillary cymes. Usually 9 to 12 flowers per cyme. Many cymes in flowersimultaneously. Flowers positioned above the foliage. Floweringcontinuous.

Natural flowering season.—Pants will flower year around regardless ofnyctoperiod, however plants flower earlier and more abundantly frommid-February until November in the Northern Hemisphere.

Flowers.—Shape: Rounded. Diameter: About 6.75 cm. Depth (height): About2.8 cm.

Flower buds.—Length: About 1.7 cm. Diameter: About 1.4 cm. Color: 145C,towards margin, 41D.

Tepals.—Arrangement: Rosette. Shape: Rounded flabellate. Apex: Rounded.Margin, outer and inner tepals: Slightly crenate. Quantity per flower:Usually about 36 per flower. Size: Outer tepals: Length: About 3.5 cm.Width: About 3.7 cm. Inner tepals: Length: About 3 cm. Width: About 3cm. Texture: Smooth, satiny, glabrous. Color: When opening, upper andlower surfaces: 41B. Fully opened, upper surface: 41B; flower colorfading to 41C to 41D with subsequent development. Fully opened, lowersurface: 41C.
